Perhaps you should try some spelling variations:
"advanced modulation using computer program" » "advanced calculation using computer program" (Expand search), "advanced oxidation using computer program" (Expand search), "advanced modulation during computer program" (Expand search), "advanced population using computer program" (Expand search), "advanced formulation using computer program" (Expand search)
"using modeling in python programming" » "using model in python programming" (Expand search), "using modern in python programming" (Expand search), "using models in python programming" (Expand search), "using modeling _ python programming" (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced modulation using computer program\") OR (\"using modeling in python programming\"))~".
• Removing quotes may allow a broader search: (( advanced modulation using computer program ) OR ( using modeling in python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced modulation using computer program") OR ("using modeling in python programming"))*.
